Power quality also affects the stable operation of the system.The power supply used for the system must not only ensure the stability of the voltage,but also ensure that when one power supply fails,it can be switched to another power supply without disturbance,otherwise it will interfere with the system operation.Switching between process control processor master/standby processors can also sometimes cause disturbances.In addition,high-power radio communication equipment such as mobile phones and walkie-talkies can easily cause interference and endanger the operation of the system when working.

电源质量同样影响系统的稳定运行。用于系统的电源既要保证电压的稳定，也要保证在一路电源故障时，无扰切换至另一路电源，否则会对系统工作产生干扰。过程控制处理机主/备处理机之间的切换有时也会导致干扰。另外，大功率的无线电通信设备如手机、对讲机等在工作时，极易造成干扰，危及系统运行。
